A Talbot-Lau X-ray Deflectometer (TXD) was implemented in the OMEGA EP laser facility to characterize the evolution of an irradiated foil ablation front by mapping electron densities >1022 cm-3 by means of Moiré deflectometry. The experiment used a short-pulse laser (30-100 J, 10 ps) and a foil copper target as an x-ray backlighter source. In the first experimental tests performed to benchmark the diagnostic platform, grating survival was demonstrated and x-ray backlighter laser parameters that deliver Moiré images were described. The necessary modifications to accurately probe the ablation front through TXD using the EP-TXD diagnostic platform are discussed.

为 OMEGA EP 激光器实​​施 Talbot-Lau X 射线偏转仪诊断平台

Talbot-Lau X 射线偏转仪 (TXD) 在 OMEGA EP 激光设备中实施，以通过莫尔偏转测量法绘制大于 1022 cm-3 的电子密度来表征辐照箔烧蚀前沿的演变。该实验使用短脉冲激光器 (30-100 J, 10 ps) 和箔铜靶作为 X 射线背光源。在对诊断平台进行基准测试的第一次实验测试中，证明了光栅的存活率，并描述了提供莫尔图像的 X 射线背光激光器参数。讨论了使用 EP-TXD 诊断平台通过 TXD 准确探测消融前沿的必要修改。
